1. Introduction
This adapter board supports 5MP and 8MP since the old multi-camera adapter board doesn’t work with Raspberry Pi 8MP IMX219 pi camera due to the camera driver issue. Now Arducam team designed upgrade the multi-camera adapter board for both 5MP and 8MP pi cameras. Consider that the high speed CSI camera MIPI signal integrity is sensitive to long cable connection, the new adapter board can only connect maximum 4 cameras to a single pi board. Because it covers the most of the use cases like 360 degree view photography and surveillance, and add more cameras will degrade the performance of the cameras. Like always please note that Raspberry Pi multi camera adapter board is nascent product that may have some stability issues and limitations because of the cable’s signal integrity and RPi’s closed source video core libraries, so use it on your own risk.

Installation
sudo apt-get update sudo apt install -y python3-kms++ python3-libcamera sudo apt install -y python3-pyqt5 python3-prctl libatlas-base-dev ffmpeg sudo pip3 install numpy --upgrade sudo pip3 install picamera2
Configuration
If you are running the latest version of Raspberry Pi OS. (January 28th，2022 or later releases, Debian version:11(Bullseye)). You need to update the config file and use libcamera apps.
- For Raspberry Bullseye users running on Pi 4, please update the following:
sudo nano /boot/config.txt Find the line: camera_auto_detect=1, update it to: camera_auto_detect=0 dtoverlay=imx219 #for Arducam IMX219 cameras dtoverlay=imx477 #for Arducam IMX477 cameras Save and reboot.
- For Bullseye users running on Pi 0 ~ 3, please also:
Open a terminal Run sudo raspi-config Navigate to Advanced Options Enable Glamor graphic acceleration Reboot your Pi
If you encounter the display issues, please also execute the following steps:
Open a terminal Run sudo raspi-config Navigate to Advanced Options Navigate to GL Driver Select GL (Full KMS) Reboot your Pi
- For Raspberry Pi Compute Module 3/4
The latest software only supports one camera at this time, CM4 uses CAM1 by default.
Add support for Pi4 B
o Just a quick post to let you know that you’ll need a new wiringPi for the Raspberry Pi 4B.
o upgrade:
cd /tmp wget https://project-downloads.drogon.net/wiringpi-latest.deb sudo dpkg -i wiringpi-latest.deb
Test
- Download the RaspberryPi library
git clone https://github.com/ArduCAM/RaspberryPi.git cd RaspberryPi/Multi_Camera_Adapter/Multi_Adapter_Board_4Channel/Multi_Camera_Adapter_V2.2_python/ sudo chmod +x init_camera.sh sudo ./init_camera.sh
Running your RPiCameras with ArduCam
cd RaspberryPi/Multi_Camera_Adapter/Multi_Adapter_Board_4Channel/Multi_Camera_Adapter_V2.2_python/
- For the use of remote control terminals, first specify the location of the image display
export DISPLAY=:0 python previewOpencv.py
Troubleshoot
- Can’t find video0
- check if the i2c bus is normal
- add dtparam=i2c_vc=on to /boot/config.txt,then reboot
- run i2cdetect -y 10 to check the devive’s address.
- if it does not detect the device’s address, please check the ribbon cable connection to ensure it is not reversed.
- check if the i2c bus is normal
